Category:Serial Killer

Serial Killers include villains who personally killed at least three people. They usually have "cooling off" periods in which they won't commit any murder.

Serial Killers include: Serial killers are much more dangerous than Murderers who killed only one or two people as they are more experimented and competent or alternatively less remorseful than Murderers.
 * Psychopaths who are driven to kill by madness. These villains are shown to be expert liars and master manipulators, and in many cases they are also seductive. They have a seemingly normal life when not engaging into murder. They may be obsessed with a certain topic or target a specific group of people and usually kill their victims in similar ways. They often act alone, because they are very paranoid and do not put trust in their entourage or relatives.
 * Assassins (include murderous ninjas as well). Unlike psychopaths, they are not always deluded or crazy, though many can be insane or extremely sadistic.
 * Tyrannical characters who oversaw the death of many, usually opponents or freedom fighters.
 * Terrorists who led a deadly attack in a place, usually resulting in the death of many innocent people. Worse, they can be Destroyers who kill everyone in they way when they are rampaging.
 * Cult Leaders (usually satanists) who sacrificed many people over the years.
 * Some violent vigilantes.
 * Some demons or Youkai who, once summoned, will commit multiple murder because it is in their inherent nature to kill.
 * Protective villains or In Love villains who killed several people in order to protect or revive someone.
